I'm using an extension that does exactly that¹, actually every update of the extension is mostly about then supporting more websites and asking permission to access those.
So maybe more developers could do a all sites and manually select sites option?
The extension can declare which websites it can access, but the other commenter was looking for the ability for the user to declare which websites it can access.
I just use the stock Pixel Thermometer app (actually not even sure if it's stock or you have to install it from Play Store). Some developers online have complained that there is no public API for it, which may explain lack of other apps. I have never used it for its health purpose. I only use it for objects like walls and cooking pans.
4. Unknowns Information / opensource / perfect documentation scarcity?
Something that is definitely no longer protected by patents but the original inventor / copycats haven't documented how to build it step by step and/ or insufficiently (possibly even for themselves?) and it is inherently complex?
You do understand everything is continuously sucked up everywhere right ? (I mean the pentagon mysteriously unaccounted billions have to go somewhere...)
It's not about copy the best, it's about reducing friction for someone coming from a competing product.
Hence why everyone uses the same play, stop etc "buttons" / signs on "mediaplayers" whether virtual or real. [1]
Unless your user really trusts you / doesn't have an alternative reducing friction is better than being subjectively better [2]
[1] triangle, square etc...
[2] bottom placement versus top placement of browserbar on mobile phones... From an ergonomics perspective way better but from a UX experience worse... Hence chrome changed top to bottom but was forced to change it back on android, while apple forced their users from top to bottom and didn't have to move it back
I would really like to know where you found that number and that idea...
Gaza is depending on the source 4.5 to 5.8% less populous currently and >10% less populous than had been projected.
And no Hamas didn't declare final solution. They were actively surprised how long they could kill people, makes sense given that the distance to the nearest military base was less than 50km...
However the Israeli leadership, some of who call them untermensch¹, have shrunk their living space by more than 10% making the largest, current times, concentrationcamp² even worse than it was before.
So maybe more developers could do a all sites and manually select sites option?
